NCP1601A - Power Factor Correction Controller

Pin Symbol Function 1 FB Feedback / Shutdown 2 Vcontrol Control 3 Ramp 4 CS Ramp Current Sense 5 Osc Oscillator / Synchronization 6 GND 7 Drv 8 VCC The IC ground Drive Output Supply Voltage Function This pin receives a current IFB which is proportional to the PFC circuit output voltage.

NCP1601A, NCP1601B Compact Fixed Frequency Discontinuous or Critical Conduction Voltage Mode Power Factor Correction Controller The NCP1601 is a controller designed for Power Factor Correction (PFC) boost circuits.

The device operates in fixed- frequency Discontinuous Conduction Mode (DCM) and variable- frequency Critical Conduction Mode (CRM) and takes advantages from both operating modes.

DCM limits the maximum switching frequency.

It simplifies the front- ended EMI filter design.

CRM limits t
